To solve that problem (and to keep me from having to replace expensive liners), I put a suction cup hook on the sidewall of my enclosure. After my shower, I put a plastic clip on the bottom of the liner, and hang it on the hook. I can hear it dripping into the tub (and not sticking to the wall!). This saves me big time, because I like the better brand of liners which are a little pricier, but really, this tip would apply to even a dollar store liner. No more scrubbing off the bottom of the liner, and my shower enclosure stays cleaner too.
